doesn't it have a vga or a dvi input on the projector
just hook up the cable from the computer to your projector, turn the projector on and press the source button until you find the right source and it should work
if that doesn't solve your problem i guess i don't fully understand your question
Assuming the projector has either a VGA, DVI, or HDMI input, connect your desktop to a regular monitor. Change the desktop resolution to match your projectors native resolution. Disconnect the regular monitor and connect your desktop to your projector.
